10 Questions to Ask Your Nephrologist About Chronic Kidney Disease

10 Questions to Ask Your Nephrologist About Chronic Kidney Disease 

Managing Chronic Kidney Disease (CKD) requires more than just showing up for appointments—it requires being an active partner in your care.

Because CKD is a progressive “syndrome” rather than a single disease, the more you know, the better you can protect your kidney function.

Here are 10 expert-recommended questions to bring to your next kidney clinic visit.

1. What is my current CKD Stage and eGFR?

CKD is classified into five stages based on your eGFR (Estimated Glomerular Filtration Rate). Think of your GFR as your “percent of kidney function.”

• The Scale: Normal function is 90 -120 mL/min.

• The Goal: Knowing your stage helps you understand your risk. While only 1 in 100 people with CKD will eventually need dialysis, higher stages (3B, 4, and 5) require much closer specialist monitoring.

2. What is the underlying cause of my kidney damage?

“CKD” is a broad term. To treat it effectively, you need to know why it happened. Common causes include:

• Diabetes (20%) and High Blood Pressure.

• Glomerulonephritis: Inflammation that may respond to immune-suppressing drugs.

• Polycystic Kidney Disease (PKD): A genetic condition.

• Obstructive Nephropathy: Blockages that might be reversible with surgery or a catheter.

• Unknown (30%): Often characterized by small kidneys on an ultrasound.

3. How will this affect my daily life and activity?

In early stages (Stages 1–3A), CKD rarely impacts your day-to-day routine. However, as you approach Stages 4–5, you may experience fatigue or “brain fog.” Ask your doctor what level of exercise is safe for you—staying active is generally one of the best ways to protect your heart.

4. Which medications can slow down my CKD progression?

Modern medicine offers powerful tools to “freeze” or slow kidney decline. Ask about:

• ACE Inhibitors or ARBs: These protect the kidney filters but require monitoring of your potassium levels.

• SGLT2 Inhibitors: Originally for diabetes, these are now a “gold standard” for slowing CKD in many patients.

5. Do I need a renal diet right now?

In early CKD, a “special diet” isn’t always necessary, but a low-sodium (salt) diet is universally recommended to control blood pressure.

Note: As CKD advances, you may need to limit potassium and protein. Ask for a referral to a Renal Dietitian if your GFR drops below 30.

6. How often do I need blood tests (Creatinine/GFR)?

Monitoring frequency depends entirely on your stage:

• Stages 1–2: Every 12 months.

• Stage 3A: Every 6 months.

• Stage 3B: Every 4–6 months.

• Stage 4: Every 2–4 months.

• Stage 5: Every 1–2 months.

7. What “Red Flag” symptoms should I report immediately?

While early CKD is silent, tell your doctor if you notice:

• Foamy Urine: A sign of protein leakage (proteinuria).

• Shortness of Breath or Ankle Swelling: Signs of fluid overload.

• Metallic Taste/Loss of Appetite: Signs that toxins are building up in the blood.

8. How is CKD affecting my heart and bones?

The kidneys regulate minerals like calcium and phosphate. If they fail, your bones can become brittle. Furthermore, kidneys and the heart work as a team; if one struggles, the other does too. Ask: “Are my heart and bone markers being monitored?”

9. If my kidneys fail, what are my treatment options?

If you reach Stage 5 (End-Stage Renal Failure), you have three main paths:

1. Kidney Transplant: The “Gold Standard” for quality of life.

2. Dialysis: (Haemodialysis or Peritoneal) to filter the blood mechanically.

3. Supportive (‘conservative’) Care: Focusing on quality of life and symptom control without dialysis. This is often the better option in older frail patients.

10. Are there any clinical trials or new treatments available?

Kidney research is moving fast. Ask your nephrologist if your local unit is participating in any trials for new medications or if there are emerging treatments suitable for your specific diagnosis.
